Specification of Letters Patent.

Patented Jan. 12, 1909.

Application led May 13, 1908. Serial No. 432,721.

To all whom it may concern:

Be it known that I, JAMES J. MORAN, citizen of the United States ofAmerica, residing at McKees Rocks, in the county of Allegheny and Stateof Pennsylvania, have invented certain new and useful Improvements inNut-Locks, of which the following is a specification, reference beinghad therein to the accompanying drawing.

AThis invention relates to nut locks, and the primary object of myinvention is the provision of positive and reliable means for locking anut upon a bolt, whereby the vibrations of a bolt of the materialthrough which the same passes will not loosen the nut mounted thereon.

A. further obj ect of my invention is to provide a simple, durable andinexpensive nut holding device that can be advantageously used inconnection with rail oints and similar structures. i

lWith the above and other objects in view which will readily appear asthe invention is better understood, the same consists in the novelconstruction, combination and arrangement of parts to be presentlydescribed and then specifically pointed out in the appended claims.

Referring to the drawings forming a part of this specification, Figure 1is a side elevation of my nut lock, Fig. 2 is a longitudinal sectionalview of the same, Fig. 3 is an end view of a nut lock showing the boltin cross section. Fig. 4E is a longitudinal sectional view of a nut lockillustrating the same used upon a long bolt.

In the accompanying drawings, 1 designates a bolt extending through twopieces of material 2. Upon the bolt 1 is screwed a nut 3 for locking thebolt 1 in the material Q.

The bolt 1 adjacent to the end thereof is provided with a longitudinalSlot 4 and adapted to engage in said slot is a central depending shank5, carried by a yoke 6 with the vertical arms thereof provided withrearward extensions 7 adapted to engage diametrically opposed faces ofthe nut 3. The length of the extensions 'T is substantially equal tothat of the width of the face of the nut with which the extensionengages. The extensions 7 are adapted to prevent said nut from rotatingso long as said shank 5 engages in the slot 4. The width of theextensions 7 being less than the width of the vertical arms of the yoke.To retain the shank 5 in the slot t a cotter pin 8 or similar fasteningmeans are employed.

The yoke 6 is adapted to embrace the upper half of the bolt 1 and toengage the outer end of the nut 3. In some instances the vertical armsof the yoke and the extensions 7 may not slip down upon the sides of thenut as easily as might be desired, consequently, I have provided theapex of the yoke 6 with a ridge 9 to receive a hammer blow for drivingthe nut retaining device in position.

Should the material through which the bolt passes be of less width thanthe material shown in Figs. 1 and 2 or the bolt 1 of a greater lengththan the bolt illustrated in said figures, washers 10 can be interposedbetween the material and the nut 3. This is best shown in Fig. 4.

My nut lock is made of strong and durable material and while in thedrawings forming a part of this application there is illustrated apreferred form of construction embodying my invention, it is to beunderstood that the elements therein may be changed or varied withoutdeparting from the spirit of the invention.

Having now described my invention what I claim as new, is

1. In a nut lock, the combination with a bolt formed with an opening inits threaded end, and a nut mounted upon the opening, of a yoke mountedupon the bolt and against the outer face of the nut, said yoke embodyinga shank extending through said opening and further provided with a pairof outwardly extending arms merging into a pair of vertical arms, saidvertical arms provided with rearward extensions engaging opposite sidesof the nut, said extensions of less width than the width of saidvertical arms, and means engaging in the shank for connecting the yoketo the bolt, said yoke further provided with a ridge at the apexthereof.

2. In a nut lock, the combination with a bolt having a rectangularopening in the threaded end thereof, and a nut mounted upon the bolt, ofa yoke mounted upon the bolt and against the outer face of the nut, saidyoke having a rectangular shank extending through said opening andfurther provided with a pair of outwardly extending arms terminating ina pair of vertical arms, said vertical arms formed with rearwardextensionsr engagin opposite sides of the nut, and means exteidingthrough the shank for connecting the yoke to the bolt. y

3. In a nut lock, the combination with a bolt having a rectangularopening in the threaded end thereof, and a nut mounted upon the bolt, ofa yoke mounted upon the bolt and against the outer face of the nut, saidyoke having a rectangular shank extending through said opening andfurtherVY provided with a pair of outwardly extending arms terminatingin a pair of vertical arms,

ksaid vertical arms formed withV rearward extensions engaging oppositesides of the nut, and means extending through the shank 15 forconnecting the yoke to the bolt, said oke provided with-a ridge at thetop thereoti In testimony whereof I aiiX my signature in the presence oftwo Witnesses.
